Application filed July 19,

This invention pertains to mechanismjfor simultaneously or independently operating a window and its screen, such as used in automobile doors.

The object of my invention is to provide a mechanism of sim le, durable and inexpensive construction iaving means whereby a single operating. crank may be adapted to elevate the screen and the window e ther independently or simultaneously.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims,and

illustrated in the accompanying drawings, in which: v

window frame 10 is of guide strips 14.

Figure 1 is a central, vertical, sectional view of a window sash and screen showing the manner in which my improved mecha: nism is attached thereto.

Figure 2 is a detail sectional view taken on the line 22 of Figure 1.

a Figure 3 is an enlarged, detail, sectional view taken on the line 33 of Figure 1.

- Figure 4 is an enlarged detail view of the lower end of the window.

Figure 5 is a segmental View of the win dow' screen. 1

The numeral 10 indicates the frame. of an automobile door. The upper portion of said frame is provided with'a window opening 11. That portion of the frame 10 below the said opening 11 is provided with side members 12 and 13. Each vertical edge member of the provided with a pair lidably mounted between the guide strips 14 is .a screen supporting frame 16. Each edge of said frame is provided with a vertical channel 15. The top ends of the members 15 are provided with a cross bar 17 which forms the top part of the screen frame. The outer face of the lower .21 having at its central portion a horizontally arranged slot 22. Mounted in the lower end of the side member 12 is a stub shaft 23 on which is rotatively mounted a sprocket 24,

said sprocket being supported between the window glass and the member 12. Mounted in the upper end ofthe member 12 is a bearing 25 in which is rotativel mounted a crank shaft 26, the inner end of saidjcrank shaft being provided with a sprocket wheel '27.

The sprockets 24 and 27 are designed to carry a sprocket chain28. The chain 28 is provided with an outwardly projecting pin 29 designed to extend through the slot 22 of the member 21. Said pin 29 is provided with a roller 30.

This provides means whereby if the sprocket 27 is rotated through the crank 26, the pin 29 will be caused to travel upwardly or downwardly and to carry with it the window glass 20, which will slide in the channel 15 or between the guide strips 14.

By this arrangement it .will be seen that the screen frame 16, which includes the channels 15, may be elevated or loyvered independently of the glass or vice-verse,

For elevating and lowering the screen, I have provided a cross bar 31, "the "ends of which are provided with outwardly extending portions 32, designed to be secured to the inner face of the channels 15. The bar 31 is mounted betweenthe chain 28 and the member 12, and designed to move upwardly and downwardly between the shafts 23 and 26. The outer face ofthe bar 31 is provided with a U-shaped spring 33, having its lower ends bent to form a recess 34, said spring being secured to the bar 31 by ascrew 35. The inner edge of the chain 28 is provided with an inwardly projecting pin 36 designed to be moved into position in the recess 34 when the saidchain has been rotated to a certain position of its movement, after which the screen frame may be elevated or lowered by the pin 36, and b rotating the crank 26. The screen 19 and t e window glass 20 are designed to operate through a slot 37 in the bottom edge of the window frame.

The operation of my device is as follows: Assuming that the window glass 20 is moved to its elevated position, as shown in Figure 1, and that the screen 19 is at its lower limit of movement, and that the pin 36 has been rot-ated to position where it has entered the recess 34 of the spring 33, this is the normal po- Assuming that it is 7 as shown in Figure 2, to be elevated, causing the screen frame to be elevated and the window 20 to be lowered, the window sliding in the channel of the members and said channels sliding between the guides 14. This operation continues until the upper edge of the bar 31 engages the bearing member 25, after which a pin 38 is moved inwardly to engage the lower edge of the bar 31. This leaves the screen in an elevated position and the window glass in a lowered or open position. 6

Assuming that it is desired to partially close the window and at the same time retain the screen in its elevated position, the operator grasps the crank 26 and turns it in a counterclockwise direction, which will cause the pin 36 to disengage the spring 38, said bar 31 being locked in its elevated position by the pin 38. It will then be seen that the window may be elevated or lowered any desired amount. The screen may again be lowered by first moving the Window to its lower limit of movement, which will again bring the pin 36 into the recess 34, after which the pin 38 will be drawn outwardly and the screen free to move downwardly and the window elevated at the same time.

It will be seen that when the channel members 15 are at their lower limit of movement and the glass is in its elevated position of movement, said glass will be retained loosely between the guide member 14. To prevent rattling when the window is in its elevated position, I have provided in each of the guide members 14 a spring 39. These springs also prevent rattling of the screen frame when in its elevated position.

Thus it will be seen that I have provided a mechanism of simple, durable and inexpensive construction, having a single operating crank by means of which the window and screen may be elevated either independently or simultaneously.

I claim as my invention 1. In a device of the class described, a window; frame having guide members, a screen frame slidably mounted between said guide members, said screen frame including a pair of oppositely disposed channel members, a window pane slidably mounted in said channel members, an endless flexible member hav-. ing parallel runs supported adjacent to one side of said window and screen frame, means for operating said endless flexible member,

and means carried by said endless member for independently or simultaneously operating said window and said screen frame.

2. In a device of the class described, a window frame having guide members, a second frame slidably mounted between said guides, said second frame including a pair of oppositely'disposcd channel members, a window closer device slidably mounted in said channel members and a window closer device carried by said slidable frame, and means for independently or simultaneously moving said window closer devices to open-or closed positions.

3. In combination, a window frame, including oppositely disposed guide members, a frame member including a pair of channel bars supporting a closer for window openings, said channel bars being slidably mounted in said guides, a second closer for window openings slidably mounted in said channel members, means for simultaneously' or independently operating said closers for window openings, con iprisin g an endless flexible member having parallel runs, means for mounting and operating said flexible member, a pin carried by one edge of said flexible member for operatively connecting the second said closer for window openings, a pin in the opposite edge of said flexible member for operatively connecting said slidable frame, and means fol detachably connecting said slidable frame with the last said pin.

1. In combination, a window frame including oppositely disposed guide members, a frame member including a. pair of channel bars supporting a closer for window openings, said channel bars being slidably mount 4 ed in said guides,-a second closer for window openings slidably mounted in said channe members, means for simultaneously or independently operating said closers for window openings, comprising an endless flexible men ber having parallel runs, means for mounting and operating said flexible member, a p n carried by one edge of said flexible member for operatively connecting the second said closer for window openings, a pin in the opposite edge of said flexible member for operatively connecting said slidable frame, means for detachably connecting said slidable frame with the last said pin and a locking pin for retaining the slidable frame in its upper limit of movement.
